Hold Attorney General Eric Holder in contempt? Not so fast, says House Republican leadership.

Speaker John Boehner of Ohio, Majority Leader Eric Cantor of Virginia and Majority Whip Kevin McCarthy of California have decided to slow Rep. Darrell Issa’s drive to hold the attorney general in contempt over the controversial Fast and Furious program, a move that could infuriate conservatives who have been calling for Holder’s resignation.

The delay could be a month or even longer, according to lawmakers and aides familiar with the issue.

Some within House GOP leadership circles would like Issa to abandon his plan for a committee and floor vote, which was sparked by a 64-page memo last week, which laid out the case for contempt.

They fear negative political fallout from citing the U.S. attorney general with contempt of Congress in an election year.

House GOP leaders are remaining mum on their plans. On Wednesday, Boehner, Cantor and McCarthy met privately — without any staff present — to discuss how to handle what many House Republicans complain is a glacially slow investigation into the scandal, according to several sources with knowledge of the meeting. Under the Fast and Furious program, federal agents allowed roughly 2,000 guns illegally purchased in the United States to “walk” to Mexican drug cartels as part of a botched plan to track down who was behind the purchases. Two U.S. law enforcements agents, as well as dozens of Mexican citizens, were killed by weapons obtained through the program.

Republican leaders are pushing Issa to do more committee work and to build bipartisan support for the contempt resolution before they let it come to the floor for a vote.

But Republican leadership’s resistance to a contempt vote is a major development in the Fast and Furious scandal and one that risks the wrath of the conservative movement. The botched federal program has become a cause célèbre for conservatives, who cite it as an example of what they consider a corrupt and reckless government.

Issa, in an interview with POLITICO, said he’ll disburse his 64-page memo on the issue to Democrats and make his staff available for further information. Issa alleges that Holder and senior Justice Department officials have failed to turn over enough documents about the controversial Fast and Furious operation or make key witnesses available for interviews.

Yet despite the detailed committee memo and more than a year of hearings, GOP leaders still don’t think the case is “rock solid,” according to an aide.

The three top House Republicans are worried about both the legal and political implications of the move, especially six months before what is already expected to be a razor-close election. And now, committee sources say they’ll have to wait at least another month — or even longer — before the panel even brings up the contempt measure.

“To date, we’re not getting new [documents] from the administration,” Issa said in an interview with POLITICO. “I’m hoping that Democrats will go to the president or Holder and say, ‘Hey, we disagree; we think you do need to provide certain information.’ Is it good to be cautious and reluctant in pressing an issue like this? Yeah.”

Issa also said he’s still working with whistleblowers who have come forward with information on the program, a joint effort between DOJ and the Bureau of Alcohol, Tobacco, Firearms and Explosives. And he’ll meet with Democratic leadership, too. The administration says it's working on complying with Issa’s request.

“I’m more likely to meet with [House Minority Whip] Steny [Hoyer] next than with [Cantor] because we’re trying to get cooperation,” Issa said. “We’re not trying to make this a partisan issue. It was a felony stupid operation, and that’s … more or less been said by people in both parties.”

Boehner declined to comment to a reporter in the Capitol on Wednesday. Cantor, who is responsible for committee chairs, told POLITICO to “stay tuned.” A Cantor spokesman said he was unavailable for an interview Wednesday, and his staff has permanently canceled the majority leader’s weekly pen and pad. McCarthy’s office also declined an interview request.

The committee didn’t predict the situation to play out this way. Earlier this week, members of Issa’s investigatory panel were hoping to vote next week to hold the attorney general in contempt for not sending requested information to Capitol Hill.

Issa said he’s proceeding with making the case that more cooperation is needed from the Justice Department in order to finish the probe.

Democrats aren’t hot on the investigation. Many of them have said Holder and the Obama administration should be more responsive, but many think that the issue should spark a debate about gun control.

Maryland Rep. Elijah Cummings, the top Democrat on the Oversight and Government Reform Committee and a frequent Issa critic, said he remains hopeful that a compromise can be worked out with the Justice Department and White House without requiring a contempt vote by the panel or the full House.

“I think Holder and the [Justice Department] have made a good-faith effort to try to work with the committee, and I am sure they will continue to do so,” Cummings said. “I know for a fact that Holder has expressed a desire to work with the committee, and I’m confident he’ll continue to do that. I’m confident that in the end, it will all work out.”

Republicans on Issa’s committee are hardly being as sympathetic with leadership’s thinking. Rep. Mike Kelly, a Republican from northwest Pennsylvania, said he’s quizzed constantly at home about why Congress isn’t doing more to hold the attorney general accountable.

“I don’t have concerns about being cautious,” Kelly said. “I go back to my district and walk into my small towns and those churches, school and workplaces, and they ask me, ‘Why? What are you waiting for? What’s the holdup to take the next step?’”

Kelly suggested leadership speak to the rank and file because they’re disconnected from real Americans, who are up in arms about the gun-walking program.

“Sometimes, there’s a disconnect,” he said. “It’s good for leadership to have discussions with us. They don’t have [the] same flexibility we do. I look at their schedules, and I think, ‘Oh my God.’ I’m more of a guy deeply rooted in the district.”

Other members of the oversight panel have also publicly called on their leadership to move the contempt resolution.

“Congress has been patient — indeed, too patient, in my judgment — with the Department of Justice and its failure to comply with the lawful request for the production of documents,” Rep. Trey Gowdy (R-S.C.) said in a statement May 3. ”I understand that for some, everything is political. Surely the Department of Justice can rise above petty, partisan politics and comply with a subpoena. The Department of Justice expects others to comply with subpoenas, yet they will not do so themselves.”

The House approved an amendment to the DOJ budget on Tuesday that calls for $1 million to be stripped from the department’s budget over its failure to comply with the Oversight and Government Reform subpoena issued last October. DOJ’s budget is $28 billion overall in 2012.
